continuation and part of the chute. rubbish, offal and the like, in cities, it is imchamber and the heat tends to evaporate the practical and too expensive to have the trucks or bearing vehicles to come to the incinerator at frequent intervals or to regulate the time .when they do come; therefore, it is customary for the vehicles to collect waste during a long period of hours and come to the incinerator at the end of the period. A congestion of vehicles results and each must wait its turn to unload into the incinerator.

It will be appreciated that by providing adequate hoppers at the incinerator plant, the waste may be dumped into these hoppers and then fed to the fire chambers as needed, thus releasing` the vehicles and permitting a more efficient and economical operation. After the first charges of waste have been fed through the chute, the liner casing 14:

will be constantly plugged, the plug being displaced onto the table by the next charge. The plug prevents cold air entering the lire moisture in said plug. This with the drying action on the table ll makes for better combustion, and more thorough consumption. If the waste is wet it will tend to pack in the chute, thus making even a better plug.

Various changes in the size and shape of the different parts, as Well as modifications and alterations, may be made within the scope of the appended claims.

What I cla-im, is

l. In an incinerator charging apparatus, the combination of a chute, a hopper feeding thereto, a plunger head disposed to traverse the chute and having an eXtended apron formed with an open lower portion, a support extending within the apron through said open portion, a fluid pressure cylinder carried by said support and open at its end neXt the chute, a fluid inlet at the opposite end of said cylinder, a tubular piston within the open end of the cylinder and connected to said head, and a tensioned connection to return the piston to the interior of its cylinder.

Q. In an incinerator charging apparatus, the combination with the fire chamber of an incinerator having a charging opening in one of its upright Walls, of a chute registering with the opening of the fire chamber and having an outward extension, a liner casing in said opening forming a continuation of the chute, a hopper discharging into the chute, a head having teeth traveling through the chute beneath the hopper, an apron carried by the head and having its lower por-V tion open and supported by said extension, a iiuid pressure actuated cylinder having a piston for driving the head through the chute to the charging opening, a support for the cylinder extending through the open portion of the apron, and means for returning the head from the charging opening.

In testimony whereof I aflix my signature.
